You sell a put, collect the credit, and two weeks later you’re sitting on 70% of the max profit. You tell yourself you’ll close it “when it hits my target.” Then the target comes and goes — because you were in back-to-back meetings, or because some small voice said “let it run a bit more.” A week later the trade has round-tripped back to breakeven, or worse. This is where a GTC order in options trading earns its keep: it closes the position on your terms, whether you’re watching a screen or not.
The Real Reason You Blow Up Winning Trades
It’s rarely the market that ruins a good option-selling trade. It’s you, staring at an open profit and deciding it isn’t quite big enough yet. Sound familiar? You had a plan when you sold the option — take X% of the credit and move on — but plans evaporate the moment a number is green on your screen.
Greed doesn’t feel like greed in the moment. It feels like patience, like “smart money doesn’t rush.” But an option seller who won’t take a good profit is really just gambling with a trade that was already a win. So what actually stops that pattern before it starts?
What a Standing GTC Order Actually Does For You
A Good-‘Til-Cancelled order sits on the exchange, working around the clock, until it either fills or you cancel it. Pair it with a buy-to-close instruction on a short option, and you’ve built a take-profit order that doesn’t care how you’re feeling that afternoon. You set the price once. The order does the emotional labor forever after.
This is the quiet trick behind a durable option selling strategy: remove the decision from the moment of temptation. You’re not disciplined at 2pm when the trade is up nicely and your phone is buzzing with three other things. You are disciplined right now, calmly, before any money is at stake. That’s the whole point of a standing limit order options traders can lean on — it captures your best thinking, not your in-the-moment thinking.
But a number on a screen is one thing. Does it actually change outcomes? Let’s run it through an example.
A Worked Example: The Trade That Almost Got Away
Say you sell a cash-secured put, strike price $50, 30 days to expiration, and collect $1.20 per share — $120 on one contract. Your plan, decided before you place the trade, is to buy it back once you’ve captured 80% of that credit. That means a buy-to-close limit order at $0.24, entered as GTC the moment you sell the put.
Nine days later, the stock drifts higher and volatility eases. Your option is now worth $0.23. Your standing order fills automatically — you didn’t touch anything. You’re in a client call when it happens. You’ve locked in $97 of profit in nine days, on capital that’s now free to work again.
Now picture the same trade without the GTC order. You notice it’s cheap, but you think, “It’s decaying nicely, why not squeeze out the last $24?” Two weeks pass. An earnings surprise or a market wobble pushes the stock back toward your strike. Your $0.23 option is suddenly $0.85. The trade that was a clean win is now a loss — not because your original thesis was wrong, but because you never defined the exit and let it drift.
Building the Rule Before You Sell, Not After
The order only works if the target is set before greed has a chance to whisper anything. In practice, that means deciding your take-profit level as part of the trade, not as an afterthought once it’s working in your favor.
- Decide your target profit — often a percentage of max credit — before you enter the trade.
- Place the buy-to-close GTC order immediately after your position fills, not “later today.”
- Size the order in contracts, not just price, so it matches your full position.
- Check it monthly for stale orders on positions you’ve since adjusted or rolled.
- Resist the urge to cancel it just because the trade is moving further your way.
That last point is where most people slip. Because what happens when the trade keeps running past your target — don’t you leave money on the table?
“But What If It Keeps Running My Way?”
This is the honest objection, and it deserves a real answer, not a brush-off. Yes — sometimes your GTC order fills and the option keeps decaying further, and technically you could’ve made more by waiting.
But you don’t sell options to squeeze every last cent from a single trade. You sell them to repeat a process, over and over, without a handful of blown-up trades wiping out ten clean wins. Taking profit reliably and redeploying that capital into a new trade is usually worth more, over time, than gambling on the last 15% of a decaying option — especially once you count the trades where “let it run” went the other way entirely.
The order isn’t there to maximize any single trade. It’s there to protect the average across all of them.
The Takeaway
Set your buy-to-close GTC order the moment your position fills, at a price you decided before greed showed up. That single habit does more to protect an option selling strategy than any indicator or forecast ever will. Automate the exit, and let the process — not your mood — decide when a winning trade is actually done.
Options selling carries real risk of loss, including on positions that show an open profit before they reverse. This article is for education only and isn’t personalised financial advice.
